First Contentful Paint
0.9 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid an excessive DOM size
1,159 elements
A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow)
Time to Interactive
3.1 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Defer offscreen images
Potential savings of 2 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Estimated Input Latency
40 ms
Estimated Input Latency is an estimate of how long your app takes to respond to user input, in milliseconds, during the busiest 5s window of page load. If your latency is higher than 50 ms, users may perceive your app as laggy
Eliminate render-blocking resources
Potential savings of 770 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Avoid large layout shifts
5 elements found
These DOM elements contribute most to the CLS of the page.
Avoids enormous network payloads
Total size was 1,225 KiB
Large network payloads cost users real money and are highly correlated with long load times
Serve static assets with an efficient cache policy
42 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay
170 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoids large JavaScript libraries with smaller alternatives
0 large libraries found
Large JavaScript libraries can lead to poor performance. Prefer smaller, functionally equivalent libraries to reduce your bundle size
Avoid chaining critical requests
17 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load
Serve images in next-gen formats
Potential savings of 17 KiB
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption
Keep request counts low and transfer sizes small
145 requests • 1,225 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
First Meaningful Paint
0.9 s
First Meaningful Paint measures when the primary content of a page is visible
First CPU Idle
2.8 s
First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input. [Learn more](https://web.dev/first-cpu-idle/).
Cumulative Layout Shift
0.04
Cumulative Layout Shift measures the movement of visible elements within the viewport
Minimize main-thread work
3.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Avoid long main-thread tasks
7 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Includes front-end JavaScript libraries with known security vulnerabilities
4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Total Blocking Time
300 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Avoid serving legacy JavaScript to modern browsers
Potential savings of 0 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers
Initial server response time was short
Root document took 500 ms
Keep the server response time for the main document short because all other requests depend on it
Reduce the impact of third-party code
Third-party code blocked the main thread for 360 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading
Speed Index
1.8 s
Speed Index shows how quickly the contents of a page are visibly populated
Remove unused JavaScript
Potential savings of 130 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Page load is not fast enough on mobile networks
Interactive on simulated mobile network at 13.3 s
A fast page load over a cellular network ensures a good mobile user experience
Reduce JavaScript execution time
1.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Network Round Trip Times
0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance
Largest Contentful Paint
1.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport
Server Backend Latencies
0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance
Mobile
Avoid large layout shifts

Includes front-end JavaScript libraries with known security vulnerabilities
4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Avoids enormous network payloads
Total size was 1,193 KiB
Large network payloads cost users real money and are highly correlated with long load times

Serve static assets with an efficient cache policy
48 resources found
A long cache lifetime can speed up repeat visits to your page
Tap targets are sized appropriately
100% appropriately sized tap targets
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements
Reduce the impact of third-party code
Third-party code blocked the main thread for 2,100 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading
Eliminate render-blocking resources
Potential savings of 2,240 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles

Avoid serving legacy JavaScript to modern browsers
Potential savings of 0 KiB
